Introduce Stage 1 runtime lookup diagnostics for the proxy actor base: adds ResolveProxyActorBase and ResolveProxyActorBaseByPluginLocalFormId along with helper checks (IsTestPluginLoaded, IsUsableProxyActorBase, editor/fullname helpers). The code logs plugin load status, editor-ID resolution, and a plugin-local FormID fallback (0x0020A1) while refusing to spawn actors (runtime spawning remains disabled). Adds throttled and one-shot log flags to avoid spam and invokes the diagnostic early on the game-thread before placed-proxy fallback and remote-player selection. Documentation updated (docs/architecture.md and docs/dev-log.md) to record the new diagnostic behavior and next steps.
